Title: Data communication method
Inventor: SUKAI JUNJI
IPC: H04L69/14
Filed: 1994-03-30
Abstract: PURPOSE:To reduce the number of connection requests from a terminal equipment and to reduce the unconnectable state in requesting the connection by giving the condition on data transmission from a CPU to a terminal equipment. CONSTITUTION:When an event is generated in terminal equipments 2A, 2B and a data transmission condition is required for a CPU 1, the CPU 1 sends the data transmission conditions including various parameters for the terminals 2A and 2B. The terminals accepting this wait until the data transmission conditions are satisfied and collect the data to be sent and issue the connection request to the CPU 1. The CPU 1 sends the transmission permission if the connection is available and sends the prohibition of transmission if the connection is not available. In accepting this, the terminals 2A and 2B send data to the CPU 1 when the connection is available and send a re-connection request when it is not available. As the result, the number of communications between the CPU 1 and the terminals 2A and 2B can be reduced and when a connection is requested, and the possibility of reject can be reduced.

Title: Method of controlling semiconductor diffusion temperature
Inventor: HIRAO MITSURU
IPC: H01L21/00
Filed: 1979-05-21
Abstract: PURPOSE:To accurately reproduce a furnace temperature without correcting it, by connecting a  control loop employing an optical to pyrometer, to a control loop employing a thermocouple. CONSTITUTION:Temperature sensors produce reference voltages at 13, 16 in accordance with instructions from a temperature setting unit 12. The first control loop acts to adjust a heater current  regulator 10 at 9 to equalize the thermoelectromotive force of a thermocouple 11 to the reference  voltage 16. The second control loop starts correcting the reference voltage for the thermocouple  depending on a quantity of deviation when the temperature of a furnace rises and the deviation  14 of the output of an optical pyrometer 8 from the reference voltage 13 exceeds a limit 15. Above about 800 deg.C, the characteristics of the optical pyrometer are utilized. At about 800 deg.C, the furnace  temperature is controlled by the thermocouple loop only. In slow heating and slow cooling, the  temperature is controlled almost only by the thermocouple to about 800 deg.C. In that case, correction  is gradually added by the optical pyrometer according as its output increases. According to this  method, it is not necessary to perform set temperature correction which is needed at the time of  temperature rising to 1,200 deg.C in the conventional cases. The furnace temperature fluctuates within + or -0.5 deg.C.

Title: Method for testing leakage of pipe
Inventor: ROJIYAA FUIRITSUPU ATSUSHIYUWA
IPC: G01M3/26
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for testing leakage of a plastic pipe by eliminating the effect of physical variation in the volume of pipe due to temperature variation and viscoelastic function of the pipe. SOLUTION: While recording the temperature in a reference chamber 14, the temperature in a pipe 10 and the absolute pressure in the reference chamber 14, the air is passed, under pressure, into the reference chamber 14 coupled with the pipe 10 to be tested through a valve 16. When a test pressure is reached, the valve 16 is closed and the pressure difference is measured between the pipe 10 and reference chamber 14. The valve 16 is opened in order to equalize the pressure and then it is closed again before the drift rate is measured. The operation is repeated several times. A computer 30 is used for calculating a creep prediction curve. Finally, a comparison is made in order to determine whether the pressure drift rate caused only by the creep and leakage in the pipe 10 is directed to intersect a curve or not regardless of temperature variation in the pipe 10.

Title: Power series type variable amplitude and phase transversal filter
Inventor: KAWAI KAZUO
IPC: H04B3/10
Filed: 1983-04-11
Abstract: PURPOSE:To obtain a variable amplitude and phase filter having power series characteristic comprising a transversal filter, by performing correction based on a coefficient obtained from the Fourier expansion. CONSTITUTION:The coefficient is obtained by applying the Fourier expansion to the power characteristic of the amplitude and phase characteristic represented by a power series. Then, the attenuation of the Fourier expanded coefficient is expedited by adding a characteristic of a cosine half period to the even number order of the power and that of a sine half period to the odd number order of the power. As to the amplitude characteristic, this coefficient is taken as a tap weight, and as to a phase characteristic filter, the Bessel function based on this coefficient is taken as a tap weight. Thus, the variable amplitude and phase filter having the power series characteristic comprising the transversal filter is obtained through the forming in this way.

Abstract: PURPOSE:To generate various pitch changing triangle waves and saw-tooth- waves with simple constitution. CONSTITUTION:An inversion instruction signal SPCTL of two bits is inputted to a register. The musical sound data are inputted from the circuit of the prestage with plural bits (code bit of one bit, amplitude bit of plural bits), and are inputted to one side terminals of respective XOR circuits. Further, the SPCTL is inputted to the other side terminals of the XOR circuits. The high- order bit of the SPCTL is inputted to an XORR circuit corresponding to the code bit, and the low-order bits of the SPCTL are inputted to plural 1XOR circuits corresponding to the amplitude bit. When the corresponding bit of the SPCTL is '1', the bit is inverted by the function of the XOR circuit, and when the corresponding bit of the SPCTL is '0', the bits of the musical sound data as it is are outputted. Thus, a waveform of one signal data is revised to plural kinds.
